Answer:
1. Mountains are the world's “water towers,” providing 60-80% of all freshwater resources for our planet. At least half of the world's population depends on mountain ecosystem services to survive – not only water, but also food and clean energy.
2. Population pressures and the expansion of intensive agriculture have forced smallholder farmers to move higher towards marginal areas and steep slopes, sparking a loss of forests, warns Mountain Forests in a Changing World.
3. Subsistence farming, form of farming in which nearly all of the crops or livestock raised are used to maintain the farmer and the farmer's family, leaving little, if any, surplus for sale or trade. Preindustrial agricultural peoples throughout the world have traditionally practiced subsistence farming.
4. Death, injury, sexual violence, malnutrition, illness, and disability are some of the most threatening physical consequences of war, while post-traumatic stress disorder (PTSD), depression, and anxiety are some of the emotional effects.
5. Healthy ecosystems clean our water, purify our air, maintain our soil, regulate the climate, recycle nutrients and provide us with food. They provide raw materials and resources for medicines and other purposes. ... Biodiversity is the key indicator of the health of an ecosystem.
